The Port of Seattle has completed an environmental analysis and prepared a State Environmental Policy Act (SEPA) Checklist for Sea-Tac Airport’s draft Part 150 Noise and Land-Use Compatibility Study, and says that environmental impacts of the Part 150 Study are “not significant.”
The Part 150 Study evaluates existing noise levels, predicts noise for the next five years and recommends programs to minimize noise impacts on Sea-Tac Airport’s surrounding communities.
For all documentation connected to the Part 150 Study including the environmental analysis and SEPA checklist, visit the study’s website.
The Port’s SEPA DNS may be appealed by filing a writ of review in King County Superior Court by Sept. 18 pursuant to Port of Seattle Resolution No. 3650.
